Strava Segment

It may be ok for road bikes but when you are looking to improve your times on rocky trails or tricky descents I think the maximum font size you see is the standard output data. The font used for the segments is too small and you can't see anything so it's of no use. Only if I go on a wide road without a lot of bumps and not too fast.

When detecting the desired route type as “trail” the source of this data should be enlarged, at minimum the improvement of your time +/- X sec . If it is very complicated at least in the full screen that the fields with the times are double or triple the size and can be read with extreme vibrations.
In those descents I can see my heart rate or speed but nothing of the segment. In descents the graph is not very useful so I would let the user choose if he wants to see the level graph or just the 3 numerical fields in large or a line without level with the ghosts of the opponents. The Garmin system with the vertical line and the 2 times on my 540 with the white background and black fonts is readable.

Your screen is nicer but in those moments of high vibrations it is useless. In those cases it is better to give large high contrast fields than something with nice colors and design.
